a system where you would search for positive things and reward them. I feel you would have a better chance of preventing spam reaching the main boards with that system than removing it once it is there.
The system is called merit and it works except for a few knuckleheads who think it's for "fun and friends".
Yet shitposts still need to be removed. Those are not mutually exclusive things.
I mean if you reported every low quality post in alt discussion it would be quite a nightmare because some are not exactly low quality enough to be spam but on the other hand many parrot the same message over and over in a slightly different way. I mean deleting them is kind of cruel because to some they may have made some effort to express themselves and to get it deleted could be genuinely like a smack in the face.
No, it's not cruel. Parroting is not a universal human right. If you're still on a mission to improve merit awards in Alts this is the course of action you should take. Clean that shit up. Stop being butthurt about merits in Meta. Those merits are not the reason why shitcoiners don't get merited.
